This CLE course will provide an in-depth look at ASTM E1527-21, the ESA standard now recognized by the EPA as satisfying all appropriate inquiries (AAI) requirements. The panel will examine how this standard has been implemented and its impact on site assessment and the due diligence process since it was approved by the EPA effective February 2023. The panel will offer best practices for practitioners when guiding clients through the due diligence process and for AAI compliance to limit CERCLA liability.

Description
Federal and state environmental laws can impose significant liabilities on parties buying or leasing commercial real estate unless they qualify for one of the liability defenses. Property owners and operators must perform an AAI--commonly known as a Phase I Environmental Site Assessment (ESA)--before taking title or possession of a property to qualify for at least one of the liability defenses available.
The EPA approved ASTM E1527-21 as the ESA standard that satisfies AAI requirements, effective Feb. 13, 2023. The standard made significant revisions compared to its predecessor, ASTM E1527-13. Effective February 13, 2024, ASTM E1527-13 no longer may be used to satisfy AAI requirements. Compared to its predecessor, the current standard provides more guidance on conducting historical reviews of the subject property and adjoining properties, revises key definitions, and clarifies the role of emerging contaminants such as PFAS in ESAs.
Listen as our expert panel examines the current standard and addresses its impact on site assessments and the due diligence process in the year since it has been approved by the EPA. The panel will also offer best practices for AAI compliance to limit CERCLA liability and for guiding clients through the due diligence process.
